In this 1977-built home in Orange, CT, radon levels reached 4.8 pCi/L — right at the threshold where action is recommended. We installed a two-pipe mitigation system in the cement foundation, which included one foundation and one crawl space.The homeowner also discussed potential well water testing and showed interest in a Sedona dehumidifier system with ducting options. A sample bottle is available on the truck in case the client opts to proceed with the water test.
